ROBERT L. BmINETT, OF N YORK, N. Y.

FUEL MIXER.

Application led January 17, 1923. Serial No. 613,189.

T o all whom t may concern.'

Be it known that I, ROBERT L. BENNETT, a citizen of the United States, and a resident of the city of New York, borough of the Bronx, in the county of Bronx and State of New York, have invented a new and Improved Fuel Mixer, of which the following is a full, clear, and exact description.

My invention relates to a mixer, and aims to provide a device of this character more particularly adapted for use in connection with the preparation of a fuel charge, such as is utilized in an internal combustion ene. guilt is a well appreciated fact that the boiling point ofvolatile fluids such as gasoline, has been constantly decreasing for a number Thus it has been increasingly diicult to provide a fuel mixture in which the maximum amount of power will be presented to the consumin element.

For this reason, a number of de ects have presented themselves, to wit, that an excess of fuel was necessary to permit of the production of a fuel mixture capable of giving satisfactory results, and due to the necessity of the utilization of this excess, a great amount of carbon deposits have formed in the consuming element resulting in an inefficient operation.

Also this excess of fuel, has, in the case of internal combustion engines worked past the pistons and diluted the lubricating oil, which, as is known, results in serious damage to the working parts of the engine.

Further, if the proportion of fuel utilized is reduced, it is also well known by those conversant with the art, that the engine will be incapable of ready acceleration, and will not develop its maximum power output.

This is to be attributed to the fact that, as aforestated, the fuel is not readily vaporized, and if the proper proportions are utilized, it will be found that the yparticles of the fuel will not be evenly distributed, thoroughly broken up, `and intimately co-mingled 1n the iuid -acti as a vehicle, and producing with the flui fuel, the fuel mixture desired. Thus, incident to this uneven distribution, and the low vaporizing qualities -of the fuel, a great amount of the same will be deposited in the form of drops on the fuel mixture will present pockets of rareed and densefuel content, which will result in an extremely spasmodic and inof air and fuel which will result in a more perfect combustion.

A further object of my invention isthe construction of a device of the nature stated in which particles of the fuel will be minutely subdivided, and thoroughly and evenly distributed in the fuel mixture.

Still another object of my invention is the construction of a device of the nature stated which is extremely simple in construction, and is hence capable of being manufactured at a nominal ligure.

Further objects of my invention will appear in the annexed specification, taken in connection with the drawings, which latter present` one practical embodiment of the same, and in which:

Figure 1 is a sectional plan view of my mixer, and showing the same arranged in proper relationship with respect to a fuel vaporizing and consuming element, and

Figure 2 is a sectional view taken along the line 2 2 and in the direction of the arrows indicated in Figure l.

Referring now more particularly to Figure 1, it will be noted that I have shown my invention as applied to a consuming element, presenting an intake manifold 5, and an exaust manifold 6.

Also a fuel vaporizing element 7 comprising a carburetor of any desired type is provided, and my improved mixer is arranged in interposed relationship between the fuel vaporizing element 7 and the intake manifold 5, and more particularly between the gasket enga ing yshoulders 8 usually form mg part of t ese elements.

Assuming that my mixer is to be applied to analready assembled unit, it will be seen that this may be accomplished by removing the gasket (not shown) from between the shoulders 8, and substituting in lieu thereof, a hollow lgasket 9 forming a part of my mixer.

This latter gasket is preferably annular to conform to the inner face of the intake manifold 5 and presents in its inner face an annular channel 10.

Associated with the gasket 9 and covering the channel 10, is a cap-shaped plate 11, which plate preferably mounts a screen 12 extending transversely with respect to the How of fluid, it being also noted that the plate 11 has a series of perforations 13 formed in its face, which perforations are in line with the channel 10 and provide a Source of communication between this portion of the intake manifold 5.

I also utilize, as a part of my invention, a hot air intake preferably in the nature of what is commonly kno-wn as a hot stove 14, which is coupled to the exhaust manifold 6, and has a tube 15 secured to it through which heated air may be drawn to a housing 16. Within this housing is arranged a valve seat with-which the rear valve 17 (zo-operates, thus providing an automatic regulating means for preventing a sudden in-rush of heated air into the housing 16.

A screen 18 may also be arranged within the lower end of the housing 16, and serves t0 prevent the entrance of foreign matter into the passage 19, which in turn has its outer end in communication with the channel 10.

Thus it will be seen that upon the vapor-y izer 7 functioning in the usual manner and introducing a fuel mixture into the intake manifold 5, that a regulated supply of heated air is introduced by means of the gasket 9, in the fuel mixture, at a number of different radial points, incident to the suction,l

which the fu mixture will produce within the channel 10. A

Now with a view of insurin a thorough co-mingling of the fuel partie es with the air, and an even distribution of these pardistribution of the fuel particles, and an even mixture.

From the foregoing it will be appreciated that by means of my improved mixer no alteration of structure will be necessary in a unit comprising a fuel producing and consuming element, and that the fuel mixture may be produced within the vaporizer in the usual manner, subsequent to which it Leanne will pass through theA screen 12 which will result in the particles of fuel being broken into minute particles. After this has occurred, an additional supply of heated air will be introduced into the fuel mixture in such a ratio that the mixture will embody substantially correct theoretical proportions necessary for eicient operation, and maximum power bein delivered on the part of the consuming e ement.

Finally to insure the proper distribution of the additional air within the fuel mixture, it will be seen that the blades 21 are utilized for accomplishing this purpose, it being also noted that the amount of air for insuring this proper proportion will not be exceeded by virtue of the lautomatic control established by the valve 17.

Also it will be understood that numerous modifications of structure might be resorted to without in the least departing from the spirit of my invention.

I claim:

1. A mixer, including a gasket presenting a channel in its inner face, a. cap plate covering said channel, said plate being formed with a series of perforations in line with said channel, the head of said cap plate being formed with a series of cutout portions, and plates arranged in said cutout portions.

2. A mixer, including a gasket formed with a channel in its inner face, a cap plate carried byj said gasket and having its side walls coverin said channel, said side walls 'being covere with a series of perforations in line with said channel, the head of said cap being formed with a plurality of cutout deiiector blades within said cutout portions, a housing in communication with said channel, means for introducing heated air into said housing, and a valve co-operating with a valve seat also within said housing.

3. A mixer, including a gasket formed with a channel in its inner face, a cap plate carried by said gasket and having its side walls ooverin said channel, said side walls being covere with a series of perforations in line with said channel, the head of said HPO cap being formed with a plurality of cutout deflector blades within said cutout portions, a housing in communication with said channel, means for introducing heated air into said housing, a valve co-operating with a valve seat also within said housing, and a screen arranged in advance of said valve.
